A3.7/5.0

Scored across 11 tools

Disambiguation5/5

Each tool has a clearly distinct resource and action (calculate tax, create/get customer, create/get/list product, create/get transaction, create/list refunds, ping). The descriptions explicitly clarify boundaries, such as calculate_tax being stateless versus create_transaction writing a live record. No two tools overlap in a way that would cause misselection.

Naming Consistency4/5

All tools use the numeral_ prefix and snake_case, with a consistent verb_noun pattern for almost every operation. The lone exception is numeral_ping, which lacks a noun but is a conventional health-check name, making this a minor deviation rather than a real inconsistency.

Tool Count5/5

11 tools is well-scoped for a tax/compliance API covering products, customers, transactions, refunds, tax calculation, and health checking. Each tool clearly earns its place without redundancy or bloat.

Completeness3/5

The set covers key create, get, and list operations for products, but lacks update/delete for customers, products, and transactions, and has no list_customers or list_transactions. These gaps could hinder agents needing to manage or discover records beyond creation and single-record retrieval.
